Prolonged QTc was more prevalent in children with severe malaria anemia compared to those without anemia, suggesting that children with severe malaria anemia were more prone to arrhythmias. The median cTnT value in the subjects was not significantly lower than that in controls, suggesting that children with severe malaria anemia are not prone to myocardial injury any more than those with uncomplicated malaria without anemia.
Background: Determination of abnormal blood pressure (BP) in children is dependent on comparison with normal percentile values. The commonly used National Institute of Health (NIH) standard is generated from children outside of Africa. Objective: To develop BP percentile values for Nigerian children based on BP cuff width 40% to 50% of arm circumference. Methods: Subjects were pupils from nine primary schools in Midwestern Nigeria recruited using a multi-stage sampling technique. Their BP was measured using a cuff width of 40 to 50% of arm circumference and cuff length of at least 80% of arm circumference respectively. The mean of two BP readings were taken. Hypertension was defined as systolic and or diastolic BP >95 th percentile of the study population. Results: There were 1549 subjects, aged 5 to 15 years, of which 757 (48.9%) were males. Prevalence of hypertension was 2.6%. Only age and weight were independent predictors of both elevated systolic and diastolic BP. The 5 th , 10 th , 50 th , 90 th and 95 th percentiles of Systolic and diastolic BP were generated for both males and females pupils. Conclusion: BP Percentiles have been generated using BP cuff width 40 to 50% of the arm circumference for Nigerian children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
